Whether the semi trailer is durable or not, the floor is very important. Many customers usually only care about the material of the beam and the brand of the axle etc. when they choose the semi trailers, and often ignore the choice of the floor. If the floor of a newly bought semi trailer is sunken, deformed or even cracked in less than a year, careful analysis may be that the floor was not selected correctly at the beginning.
For the trailer’s floor, it is generally divided into flat plate and checkered plate according to the shape, and high-strength steel plate and ordinary steel plate according to the material. How to choose depends on the needs of different uses.
High strength steel plate can be selected if it needs to be strong and durable. Most of the high-strength plates are flat plates. The advantages are that they will not bend easily and have good resilience. The disadvantages are that they are brittle as a whole and easy to crack under load, but they will not sag and deform. After cracking, a steel plate can be padded under the crack for repair welding. Generally, the thickness of high-strength plate is 1.5mm, 1.8mm and 2.0mm. The service time of each thickness specification can be increased for a long time, but the weight increases by about 200 kg with the increase of 1 mm. Generally, high-strength plates are mostly selected on dump trucks.
The goods that need anti-skid can choose the checkered plate. The checkered plate is mostly used in the trailer with ordinary steel plate, which can be flexible and extensible. Compared with the high-strength plate, it is generally soft and easy to sag and deform, but it has good impact resistance. Low bed semi trailers, flatbed semi trailers, container semi trailers are used more. Other models, such as Fence semi trailers, Cargo semi trailers, can effectively avoid the problem of sag and deform by using W-type bottom steel transverse balance, The checkered plate can also be laid in reverse, with the checkered facing down, which is more durable. Generally, the thickness is 2.0 mm and 2.5 mm, so the weight of the vehicle will be larger.
Stainless steel plate can be selected for high configuration vehicles. In addition to the above two kinds of materials, there is another kind of special plate, which is stainless steel plate. In recent years, with the popularity of lightweight, light weight, strong and durable cars have become the mainstream requirements. In addition to the expansion of the international chemical industry transportation market, the requirement of anti-corrosion has increased, Therefore, the stainless steel base plate came into being. It can deal with corrosive goods calmly, and it is also easy to deal with the hardness of common goods. Even in the face of rough sand and gravel, it can also play its advantages of smooth unloading and no residue. The general thickness of stainless steel floor is 1.5mm and 2.0mm, so the price will be higher.
Just now, it was mentioned that the bottom plate of the dump truck has requirements on the skid resistance. In fact, in addition to the stainless steel bottom plate, a kind of hard plastic plate has also been applied to the dump truck. Its surface is smooth, slightly elastic, waterproof and antifreeze. Even in the cold winter, it can avoid the embarrassment of goods freezing together with the bottom of the truck. In recent years, the popularity has gradually increased.
In addition to the above several materials, there is another kind of floor which is more delicate. It is widely used in logistics box cars, wingspan cars and container trailers. It is the plywood floor, which has good flatness, clean and easy to clean, and is suitable for the transportation of high-end light goods such as express logistics.
It seems that there are many kinds of trailers in the world, and the bottom plates are also various. If you choose the wrong one, the experience and service life of the trailer will be greatly reduced. Only the right one is the best one.
